# Okasaki style Functional Red Black Tree
# https://www.cs.tufts.edu/comp/150FP/archive/chris-okasaki/redblack99.pdf
#
# leaves and root are black
# BST
# No red node has a red child
# Every path from the root to a leaf has the same number of black nodes
#
# Based off Tenderlove's ruby version: https://gist.github.com/tenderlove/c843996b39e50ea6eb129871f07e589d
